What is the relation between soil conservation and food security?

Correct answer: Soil conservation supports crop production

The direct answer is A. Soil conservation protects the soil from erosion, loss of fertility, and damage, so it supports reliable crop production and food security. Step by step: healthy soil stores water and nutrients; crops need these for growth; conservation methods such as planting trees, contour ploughing, terracing, and avoiding excessive erosion keep soil productive; productive soil gives better and more stable harvests; stable harvests help provide food. Option A is correct because protecting soil supports present and future crop production. Option B is wrong because conservation generally protects production rather than reducing food, although a particular protective activity may have short-term costs. Option C is wrong because soil supplies plants with support, water, and nutrients, so it is directly related to food. Option D is wrong because food comes from plants and animals, not only minerals; minerals are nutrients or raw materials but cannot replace food production. Memory cue: save the soil today to secure food tomorrow.
